This application is a continuation of U.S. patent application Ser. No. 16/259,486 filed Jan. 28, 2019, which in turn is a continuation-in-part of U.S. patent application Ser. No. 15/401,467 filed Jan. 9, 2017 (now U.S. Pat. No. 10,294,681; issued May 12, 2019), which in turn is a continuation-in-part of U.S. patent application Ser. No. 15/377,347 filed Dec. 13, 2016, which in turn claims priority on U.S. Provisional Patent Application Ser. No. 62/271,752, filed Dec. 28, 2015, the disclosures of which are incorporated herein by reference.

The present disclosure relates generally to protective coverings, and more particularly to a protective covering for protecting finished work and other surfaces during construction, moving, painting, or other activities, and a method of manufacturing the protective covering.

BACKGROUND OF THE INVENTION

The process of building out an area or constructing a building occurs in many phases. During this process, a number of different types of workers are required and it may be necessary to complete the construction in steps. As a result, frequently contractors damage floors, stairs, countertops, and other finished work in the process of completing other tasks and moving in and out heavy equipment.

During the last stages of house or building construction, and after floor and countertop materials already have been installed, finish work such as painting, caulking, finish carpentry, and appliance and lighting fixture installation is typically done. This finish work can often cause significant damage to plastic laminates, linoleum, hardwood, ceramic tiles, and carpets before the building is finished, sold, or moved into. Heavy tools, caulking and paint buckets, and appliance edges are particularly damaging.

Traditionally, the only protection, if any, given to floors and countertops during the final stages of construction has been a thin fabric drop cloth or a thin plastic sheet such as the 0.002 inch thick self-adhesive plastic sheet. These sheets help protect against paint or caulking splatters and soil on workers' feet, but do not protect against gouges, scrapes, abrasion, or other damage and breakage due to impact of objects or moving of equipment/tools.

Fabric throw rugs or moving van-style blankets can be used but these absorb liquids, snag and catch on appliances, and do not protect against sharp and forceful impact. Also, these covers are bulky and heavy to transport and store.

Other products are designed to protect floors or walls independently, but not both at the same time with one product. These products leave the base of walls and the perimeter of the floor exposed to damage. It is to be appreciated that where separate products are used to protect the floor and the wall, the lower section of walls, including the baseboards, can be easily damaged on job sites. Additionally, present products do not protect from liquid spills occurring at or near the junction between the wall and floor.

In view of the current state of the art, an improved fiberboard sheet was developed as disclosed in U.S. Pat. No. 9,365,385 and U.S. Design Pat. No. D751,223, which are both incorporated herein by reference. Although this fiberboard sheet provides protection to a floor surface when multiple fiberboard sheets are used, the fiberboard sheets can separate from one another and expose the floor between the separated sheets. In order to address this issue, the end edges of adjacent fiberboard sheets are overlapped. However, during use of the fiberboard sheets, the sheets can move relative to one another and allow a space to form between the fiberboard sheets. Also, sawdust, screws, nails, clips, etc. that fall on the top surface of a fiberboard sheet can work its way between the overlapped sheet and onto a floor surface during the use of the fiberboard sheets. Such materials can cause damage to the floor surface once such materials are in contact with the floor surface and workers walk on the fiberboard sheets and cause such materials to be pressed into the floor surface. Furthermore, liquid spills on the fiberboard sheets can seep between the overlapped fiberboard sheets and onto a floor surface and thereby potentially damage the floor surface. Generally, a user must overlap the fiberboard sheets and then get on his/her knees and cut and paste adhesive tape over the overlapped seam of the fiberboard sheets. For many workers, getting up and down on ones knees to tape over overlapped fiberboard sheets is time consuming, can be difficult for some workers, and requires additional materials (such a tape) at the jobsite to complete the installation of the fiberboard sheet over a surface to be protected.

In view of the current state of floor coverings, there is a need for a floor covering that is easy to use, protects a floor surface against sharp and forceful impact, protects the lower section of walls (including the baseboards), and which can be easily connected together.

SUMMARY OF THE INVENTION

The present invention is directed to a surface protector formed of a sheet having an adhesive strip positioned on or closely adjacent to one or more edges of the sheet. As can be appreciated that the sheet can be formed of different types of materials (e.g., paperboard, fiberboard, plastic, fabric, composite materials, fiberglass, nylon or other types of polymers, etc.). In one non-limiting arrangement, the sheet is formed of a flexible or rollable material. As defined herein, a “rollable material” is a material having a longitudinal length of at least 10 feet that can be hand rolled by a single individual into a roll having a diameter of less than 12 inch without forming creases that run from side edge to side edge in the material as the sheet is rolled. The thickness of the sheet is non-limiting. In one non-limiting arrangement, the sheet is formed of paperboard or fiberboard. As defined herein, “fiberboard” is a type of engineered wood product that is made out of wood fibers. The general types of fiberboard (in order of increasing density) include particle board, medium-density fiberboard, and hardboard. Plywood is not a type of fiberboard, as it is made of thin sheets of wood, not wood fibers or particles. Cardboard is also not paperboard or fiberboard since it includes a corrugated layer. In one non-limiting configuration, the paperboard or fiberboard that forms the sheet of the surface protector has a thickness of less than 0.5 inches; however, this is not required. In another non-limiting configuration, the paperboard or fiberboard is generally a water-resistant paperboard or fiberboard; however, this is not required.

The surface protector can include one or more adhesive strips positioned on one or both sides of the sheet. The adhesive strip is a preapplied adhesive strip that includes a removable top protective release liner that, when removed, exposes a top adhesive surface of the adhesive strip. The exposed top adhesive surface of the adhesive strip is designed to bond with a portion of another surface protector that is positioned on the exposed top adhesive surface. The adhesive bond between the two sheets of the two surface protectors that is formed by the adhesive strip is a dust-proof bond and can optionally also be a liquid-proof bond. During installation of multiple surface protectors of the present invention, a first sheet of the surface protector is positioned on a floor surface to be covered. After the first sheet of the surface protector is positioned on a floor surface, the removable release liner is removed from the top adhesive surface of the adhesive strip. An edge of a second sheet of the surface protector is positioned over and then on the exposed top adhesive surface of the adhesive strip on the first sheet of the surface protector. Thereafter, the user can walk on the top surface of the second sheet in the area of the top adhesive surface of the adhesive strip on the first sheet to complete the adhesive bonding of the first and second sheets of the two surface protectors. The adhesive bond forms a dust-proof bond between the two surface protectors and also, optionally, a liquid-proof seal between the two surface protectors. This process can then be repeated to secure additional surface protectors together. For example, when a third surface protector is to be connected to the side of the second surface protector, the removable release liner on the second surface protector is removed from the top adhesive surface of the adhesive strip. An edge of a third sheet of the surface protector is positioned over and then on the exposed top adhesive surface of the adhesive strip on the second surface protector. Thereafter, the user can walk on the top surface of the third sheet in the area of the top adhesive surface of the adhesive strip on the second surface protector to complete the adhesive bonding of the second and third surface protectors. As can be appreciated, fourth, fifth, etc. surface protectors can be connected together if so required. This arrangement eliminates the need for users to get down on their knees to apply tape over the overlapping edges of the two surface protectors. The removable release liner can be removed from the adhesive strip prior to, during, or after the sheet being placed on the floor surface; however, this is not required. The removable liner can also be removed from one surface protector as the other surface protector is being laid over the prior laid surface protector. In such an installation method, the user need not bend completely over or get on his/her knees to adhesively connect together the two surface protector. The use of the preapplied adhesive strip on the surface protector eliminates the need to apply a separate piece of tape over the overlapping edges of two surface protectors and also makes installation of the sheets faster and easier.

The width and thickness of the adhesive strip is non-limiting. Generally, the width of the preapplied adhesive strip is 0.25-8 inches and all values and ranges there between (e.g., 1 inch, 2 inches, 2.5 inches, etc.) however, larger widths can be used. Generally, the width of each of the adhesive strips is about 0.01-10% the width of the sheet of the surface protector (and all values and ranges therebetween), and more typically about 1-8% the width of the sheet of the surface protector. The thickness of the adhesive strip is generally less than 0.25 inches; however, greater thickness can be used. The adhesive is selected and formulated such that, when the adhesive is connected to the surface of another surface protector, a dust-proof and optionally a water-resistant or waterproof seal is formed between the two surface protectors at the location of the adhesive strip; however, this is not required. The composition of the adhesive that forms the adhesive strip is non-limiting. The adhesive is selected and formulated such that when the adhesive is connected to the surface of another sheet, the connection is a permanent connection. Such permanent connection is defined such that when two surface protectors that are connected together by the adhesive strip are forcibly separated from one another, one or more surfaces of the sheets of one or both surface protectors are torn or damaged and/or the adhesive strip is damaged due to the forced separation of the surface protectors. As a result of such damage, a dust-proof seal and/or liquid-proof seal cannot be reformed along the complete length of the adhesive strip. A non-permanent connection would result in the surface protector and adhesive strip not being torn or damaged due to the separation of the two sheets.

In one non-limiting aspect of the invention, the width of the releasable release liner is generally the same or slightly greater than the width of the adhesive strip. Generally, the width of the adhesive strip and releasable release liner are constant along the longitudinal length of the surface protector; however, this is not required. The thickness of the releasable release liner is generally greater than the thickness of the adhesive strip; however, this is not required. The material of the releasable release liner is generally different from the composition of the adhesive used to form the adhesive strip. The top surface of the releasable release liner is generally a non-stick surface; however, this is not required. The thickness of the adhesive is generally less than the thickness of the sheet of the surface protector; however, this is not required. The thickness of the releasable release liner is also generally less than the thickness of the sheet of the surface protector; however, this is not required. In one non-limiting arrangement, the thickness of the adhesive strip is no more than 0.25 inches; however, this is not required. In one specific configuration, the thickness of the adhesive strip is no more than about 0.05 inches. In another non-limiting arrangement, the thickness of the releasable release liner is no more than 0.2 inches; however, this is not required. In one specific configuration, the thickness of the adhesive strip is no more than about 0.1 inches.

In another non-limiting aspect of the invention, one or more adhesive strips are positioned on or adjacent to one or both side edges of the sheet of the surface protector; however, this is not required. In one non-limiting embodiment, the sheet of the surface protector only includes a single adhesive strip positioned along one side edge of the sheet. The adhesive strip can be positioned on the side edge or spaced at some distance (e.g., 0.01-5 inches, etc.) from the side edge of the sheet of the surface protector. Generally, the adhesive strip is positioned parallel to the side edge; however, this is not required. In an additional or alternative non-limiting embodiment, the sheet of the surface protector includes two or more adhesive strips positioned along one side edge of the sheet. One of the adhesive strips can be positioned on the side edge or spaced at some distance (e.g., 0.01-5 inches, etc.) from the side edge of the sheet of the surface protector. The one or more other adhesive strips can be positioned next to one another or be spaced from one another (e.g., 0.01-4 inches, etc.). Generally, the adhesive strips are positioned parallel to one another; however, this is not required. Generally, the adhesive strips are positioned parallel to the side edge of the sheet of the surface protector; however, this is not required. In an additional or alternative non-limiting embodiment, the sheet of the surface protector includes one or more adhesive strips positioned along each of the two side edges of the sheet. One of the adhesive strips can be positioned on the first side edge or spaced at some distance (e.g., 0.01-5 inches, etc.) from the first side edge. Another of the adhesive strips can be positioned on the second side edge or spaced at some distance (e.g., 0.01-5 inches, etc.) from the second side edge. If the sheet of the surface protector includes two or more adhesive strips at or near the first and/or second side edges of the sheet, the one or more other adhesive strips can be positioned next to one another or be spaced from one another (e.g., 0.01-4 inches, etc.). Generally, the adhesive strips are positioned parallel to one another; however, this is not required. Generally, the adhesive strips are positioned parallel to the first and/or second side edges of the sheet of the surface protector; however, this is not required. In an additional or alternative non-limiting embodiment, the sheet of the surface protector includes one or more adhesive strips positioned on a top surface of the sheet and along one or both side edges of the sheet and one or more adhesive strips positioned on a bottom surface of the sheet and along one or both side edges of the sheet. In such an arrangement, the top or bottom surface of the sheet can face a floor surface and the side opposite the floor surface would have one or more adhesive strips that could be used to connect to another sheet. As can also be appreciated, one or more adhesive strips could be used to facilitate in securing one surface of the sheet of the surface protector to a floor surface and the one or more adhesive strips on the opposite side of the sheet could then be used to connect to another sheet. The positioning of the one or more adhesive strips on the top and bottom surfaces of the sheet of the surface protector can be spaced the same or different distances from the first or second side edges of the sheet. The orientation of the one or more adhesive strips on the top and bottom surface of the sheet can be the same or different from the adhesive strip configuration discussed above. In an additional or alternative non-limiting embodiment, the sheet of the surface protector includes one or more adhesive strips positioned along the front edge and/or end edge the sheet. Generally, the sheet has a first and second side edge that runs along the longitudinal length of the sheet. Generally, the first and second side edges are parallel to one another; however, this is not required. The front edge and end edges run between the first and second edges of the sheet and are generally normal (e.g. 80°-110°) to the two side edges. Generally, the front and end edges are parallel to one another; however, this is not required. In one non-limiting configuration, one of the adhesive strips can be positioned on the front edge or spaced at some distance (e.g., 0.01-5 inches, etc.) from the front edge. Likewise, one of the adhesive strips can also or alternatively be positioned on the end edge or spaced at some distance (e.g., 0.01-5 inches, etc.) from the end edge. One or more other adhesive strips can be optionally positioned next to one another or be spaced from one another (e.g., 0.01-4 inches, etc.). Generally, the adhesive strips are positioned parallel to one another; however, this is not required. Generally, the adhesive strips are positioned parallel to the front edge and/or end edge of the sheet; however, this is not required. The one or more adhesive strips that are positioned at or near the front edge and/or end edge can be positioned on the top and/or bottom side of the sheet of the surface protector. In one non-limiting configuration, one or more adhesive strips are positioned on the top side of the sheet at or near the front edge and/or end edge. In another non-limiting configuration, one or more adhesive strips are positioned on the bottom side of the sheet at or near the front edge and/or end edge. In another non-limiting configuration, one or more adhesive strips are positioned on the top and bottom sides of the sheet of the surface protector at or near the front edge and/or end edge. In another non-limiting configuration, one or more adhesive strips are positioned on the bottom side of the sheet of the surface protector at or near the front edge and one or more adhesive strips that are positioned on the top side of the sheet at or near the end edge. In another or alternative non-limiting configuration, one or more of the adhesive strips that runs between the side edges of the sheet of the surface protector is positioned between one of the adhesive strips positioned on or closely to the front edge and to one of the adhesive strips positioned on or closely to the end edge. Generally, the one or more adhesive strips positioned between the adhesive strips located at or near the front and end edges of the sheet are positioned generally parallel to the front and/or end edges and/or generally parallel to the adhesive strips located at or near the front and end edges of the sheet; however, this is not required. Generally, the one or more adhesive strips positioned between the adhesive strips located at or near the front and end edges of the sheet are spaced from one another (e.g., 0.5-50 ft. and all values and ranges therebetween); however, this is not required.

In another non-limiting aspect of the present invention, the width of the adhesive strip is generally about 0.25-8 inches (and all values and ranges therebetween); however, larger widths can be used. Generally, the width of each of the adhesive strips is about 0.5-10% the width of the sheet of the surface protector (and all values and ranges therebetween), and more typically about 2-8% the width of sheet of the surface protector. The width of the releasable release liner is generally the same or slightly greater than the width of the adhesive strip. Generally, the width of the adhesive strip and releasable release liner are constant along the longitudinal length of the surface protector and generally run parallel to an edge of the sheet of the surface protector; however, this is not required.

In another non-limiting aspect of the present invention, the sheet can optionally include one or more embedded creases, wherein each of the creases can be folded in order to position a portion of the sheet horizontally and another portion of the sheet vertically. The term “crease” used herein includes scoring or perforating the surface of the sheet of the surface protector. The one or more creases can provide a quick and easy folding of the sheet of the surface protector, along one or more crease lines, to allow for simultaneous horizontal and vertical protection within a single product. The one or more creases in the sheet of the surface protector can eliminate the need for two or more separate products and extra steps in the protection process. The surface protector can create a seamless barrier between a horizontal and a vertical junction of orthogonally adjacent surfaces such as, for example, a floor and a wall extending upwardly therefrom. The one or more creases (when used) can be located only on the top surface of the sheet of the surface protector, only on the bottom surface of the sheet of the surface protector, or on both the top and bottom surface of the sheet of the surface protector. The one or more creases formed in the sheet of the surface protector are designed to enable the sheet to be folded along the crease without causing the sheet to tear or separate along the crease. A very durable, bendable and flexible material for the sheet can be used. In the past, the folding of paperboard or fiberboard used for surface protection of floor surfaces commonly resulted in the breakage or improper bending of the paperboard or fiberboard, thus making it undesirable for a floor protection system. Cardboard has been used in the past since it can be easily folded; however, cardboard is not as dense and durable as fiberboard of the similar thicknesses and subsequently does not provide for the desired floor protection in many applications. The number of creases on the top and/or bottom of the sheet of the surface protector is non-limiting (e.g., 1-20 creases, 2-10 creases, 2-5 creases, 3 creases, etc.). The number of creases may vary due to the custom needs of users. Generally, one or more creases run along the longitudinal length of the sheet of the surface protector; however, this is not required. In one non-limiting configuration, the sheet of the surface protector includes two generally parallel sides that run along the longitudinal length of the sheet and one or more creases run generally parallel to the sides. When two or more creases are used on the sheet and run along the longitudinal length of the sheet, the two or more crease are generally parallel to one another; however, this is not required. The one or more creases (when used) are offset a distance inward from the outer perimeter or edge of the sheet of the surface protector. Generally, each of the creases are spaced a greater distance from an edge of the surface protector than the adhesive strip; however, this is not required. In one non-limiting configuration, one side of the surface protector includes one or more creases. In another non-limiting configuration, two opposing sides of the surface protector each include one or more creases. The surface protector, when including one or more creases, is designed to be folded along the one or more creases, thereby creating a first portion and a second portion. The first portion of the surface protector protects a first surface and the second portion of the surface protector protects a second surface. The first surface is generally orthogonal to the second surface; however, this is not required (e.g., 5-150° and all values and ranges therebetween). When two or more creases are included on the sheet, each crease includes a respective offset from a side of the sheet that is different from another crease; however, this is not required. In one non-limiting arrangement, at least two of the creases are proximal to one side of the perimeter of the sheet and offset at different positions relative to one side. One or more of the creases (when used) can be perforated and/or water resistant; however, this is not required. In one non-limiting configuration, the one or more creases on the sheet of the surface protector are water resistant prior to and after the sheet is folded along the crease; however, this is not required. A creasing wheel can optionally be used to form the one or more creases in the sheet. The one or more creases in the sheet can have a depth from about 5% to about 40% of a depth of the sheet (and all values and ranges therebetween), and typically about 10-20% of a depth of the sheet. In one non-limiting arrangement, the one or more creases in the sheet of the surface protector includes a depth from about 12-16% of a depth of the sheet. Generally, the depth of the crease is constant along the length of the crease; however, this is not required. The width of the one or more creases is generally about 0.05-0.5 inches (and all values and ranges therebetween). The one or more creases (when used) are generally positioned about 1-18 inches (and all values and ranges therebetween) from the perimeter of the paperboard or fiberboard; however other distances can be used. The one or more creases can be colored to facilitate in the visual location of the crease; however, this is not required.

In another non-limiting aspect of the present invention, the surface protector can be a non-reusable (i.e., one-time use) surface protector; however, this is not required. The surface protector includes a sheet of foldable or bendable material (e.g., paperboard or fiberboard material, etc.) having a perimeter, a top surface and a bottom surface, and at least one adhesive strip. Generally, the sheet includes a front edge, a rear edge, a first side edge, a second side edge, a top surface and a bottom surface; however, this is not required. Also, the sheet generally has a square or rectangular shape when viewing the top surface of the sheet; however, this is not required. The surface protector can be in the form of a roll of surface protector or be formed in individual sheets. When the surface protector is in a roll, the roll is generally 10-200 ft. in length (and all values and ranges therebetween); however, longer lengths can be used. When the surface protector is in a roll, the material and thickness of the surface protector is selected so that the surface protector can be rolled into a roll and unrolled from the roll without damage or creasing the surface protector. Generally, the thickness of the sheet of the surface protector when in roll form is less than 0.5 inches and typically no more than 0.2 inches; however, this is not required. When the sheet is formed of paperboard or fiberboard, the sheet generally has a thickness of at least about 0.05 inches and typically no more than about 0.2 inches; however, this is not required. Such a thickness provides for the desired surface protection and water resistance generally desired for floor protection. When the surface protector is in the form of individual sheets, the surface protector is generally about 2-20 ft. in length (and all values and ranges therebetween); however, longer lengths can be used. The width of the surface protector when in a roll form or in individual sheet form is generally about 1-10 ft. (and all values and ranges therebetween); however, greater widths can be used. The surface protector is generally formed of a material that is water resistant or water impermeable. In one non-limiting configuration, the surface protector is formed of a material that prevents full penetration of water through the thickness of the surface protector for at least about 5 minutes, typically at least about 10 minutes, more typically at least about 30 minutes, even more typically at least about one hour, and still even more typically at least about 12 hours.

The invention is also directed to a method of forming the surface protector. The method can include the steps of a) providing a sheet (e.g., paperboard or fiberboard sheet) having a perimeter, and b) applying an adhesive strip at or near at least one edge of the sheet. The method can also include the steps of a) providing a sheet (e.g., paperboard or fiberboard sheet) having a perimeter, b) applying an adhesive strip at or near at least one edge of the sheet, c) optionally scoring or pressing the sheet to include one or more creases aligned generally parallel to at least one side of the sheet, and d) positioning the crease to be offset from the perimeter of the sheet.

In still another and/or alternative non-limiting object of the present invention, there is provided a surface protector that includes one or more preapplied adhesive strips and one or more creases on the top and/or bottom side of the surface protector, and which said surface protector can be easily connected to another surface protector so as to form a dust-proof or dust-resistant seal between the two adhesively connected surface protectors, and optionally a liquid-proof or liquid-resistant barrier between the two adhesively connected surface protectors, and which surface protector can be bent along the one or more creases while not damaging the crease to provide protection to floor and/or wall surfaces.

These and other objects and advantages will become apparent to those skilled in the art upon reading and following the description taken together with the accompanying drawings.

DETAILED DESCRIPTION OF THE NON-LIMITING EMBODIMENTS

Referring now to the drawings, wherein the showings are for the purpose of illustrating various non-limiting embodiments of the invention only and not for the purpose of limiting the same, the present disclosure provides a system and method for surface protection comprising a surface protector having one or more adhesive strips on the top and/or bottom surface of the surface protector which allow for a plurality of surface protectors and/or floor coverings to be connected together. This system thus eliminates the need for additional materials (e.g., tape, glue, etc.) at the jobsite to complete the installation of the surface protector. The surface protector can also optionally include one or more creases on the top and/or bottom surface of the surface protector.

Referring now to FIGS. 1-23, there is illustrated a surface protector 10 configured to protect selected portions of surfaces such as, for example, a floor F and/or a wall W. Generally, the surface protector 10 includes a sheet 11 of bendable material such as, for example, a paperboard material or a fiberboard material having a perimeter comprising edges 12, 14, 16, 18, a top surface 24 and a bottom surface 26. Additionally, the surface protector 10 includes one or more adhesive strips 20 on the top and/or bottom surface of the sheet. The adhesive strip 20 is illustrated as being positioned adjacent to one or more edges of sheet 11. As illustrated in FIGS. 1-4A, the surface protector includes a single adhesive strip positioned on the top surface 24 of sheet 11 and adjacent to and generally parallel to edge 16. As can be appreciated, the top surface and/or the bottom surface of sheet 11 can include one or more adhesive strips. As also can be appreciated, the adhesive strip can be located on edge 16 instead of being spaced from edge 16 as illustrated in FIGS. 1-4A. As can also be appreciated, one or more adhesive strips can be positioned on or adjacent to edge 12 of sheet 11.

As discussed above, the preapplied adhesive strip is illustrated as being spaced from edge 16; however, it can be appreciated that the adhesive strip can be positioned such that one side of the adhesive strip extends to edge 16. Generally, the adhesive strip 20 is a preapplied adhesive strip having a top adhesive surface 32.

As best illustrated in FIGS. 2-3, the adhesive strip 20 includes a removable top protective release liner 30 that fully covers the top surface of the adhesive strip. When the top protective release liner is removed from the top surface of the adhesive strip, as indicated by arrow A, the top adhesive surface 32 of the adhesive strip 20 is exposed and the adhesive strip is not damaged. The composition of the top adhesive surface 32 is non-limiting; however, it is typically selected to form a permanent connection or bond with another surface protector and/or floor covering. The thickness of the adhesive strip is non-limiting. Generally, the thickness is about 1 mill to 0.1 inch (and all values and ranges therebetween). The adhesive is generally formed of a flexible material such that when the surface protector is rolled into a roll and subsequently unrolled, the adhesive strip is not damaged. The top protective release liner generally has a thickness of about 5 mills to 0.1 inch (and all values and ranges therebetween). Generally, the thickness of the top protective release liner is greater than the thickness of the adhesive strip; however, this is not required. The top protective release liner is also generally formed of a flexible material such that when the surface protector is rolled into a roll and subsequently unrolled, the top protective release liner is not damaged and does not prematurely release from the top surface of the adhesive strip. Generally, the adhesive strip has a constant thickness and width along the length of the surface protector. The width of the adhesive strip is generally about 0.25-8 inches and typically about 0.5-3 inches; however other widths can be used. These features of the adhesive strips are also applicable to the adhesive strips illustrated in FIGS. 4-23.

It is to be appreciated that a section of a floor can become exposed between separated sheets of traditional floor coverings at job sites, thereby allowing dirt, debris, etc. to fall onto the floor and work their way underneath the floor coverings. The adhesive strip 20 applied to the surface protector 10 of the present invention is designed to prevent this separation of overlapped surface protectors, thereby preventing any relative movement between said surface protectors and inhibiting or preventing dirt, debris, etc. from falling thereunder. The adhesive strip can also be designed to optionally form a liquid-resistant or waterproof seal between the two connected surface protectors.

As best illustrated in FIGS. 4 and 4A, the top adhesive surface 32 of the adhesive strip 20 is capable of forming an adhesive bond with a portion of a second surface protector 70 positioned on or over the exposed top adhesive surface 32 of the adhesive strip 20. FIG. 4 illustrates two sheets 10, 70 of surface protector being connected together. FIG. 4A illustrates a roll R of surface protector 70 being unrolled and connected to a previously unrolled or previously placed sheet 10 of surface protector 70. The bond formed between the surface protector 10 and the surface protector 70 can be a dust-proof bond. Furthermore, the bond formed between the surface protector 10 and the surface protector 70 can optionally be a liquid-proof bond. In combination with the water-resistant nature of sheet 11 of the surface protector 10, there is provided a substantially dust-proof and optional liquid-proof surface protection system as illustrated in FIGS. 1-4A

Generally, the adhesive bond formed between two surface protectors is designed to be a permanent bond. As such, breaking of the adhesive bond (i.e., separating the two connected surface protectors) will lead to damage to one or both of the surface protectors connected by the adhesive bond and/or damage to the adhesive strip. For example, when the two surface protectors are separated from on another after being previously connected together by the adhesive strip and the sheets are formed of a paperboard or fiberboard material, a layer of fiberboard material or paperboard material is generally left behind on the top adhesive surface of the adhesive strip; however, this is not required. Additionally, breaking of the adhesive bond can compromise the dust-proof seal and/or optional liquid-proof seal created by the adhesive bond.

In current floor protection systems, a user must get on his/her knees and cut and paste adhesive tape over the seams between adjacent floor coverings. Such a process is time consuming, can be difficult and painful for individuals that have arthritis or bad knees and joints, and a proper connection or seal may not be formed between the adjacent floor coverings. The present invention provides a surface protector floor covering that is easy to use, capable of protecting a surface (e.g., floor F) against sharp and forceful impact, and can be easily connected together.

Any number of adhesive strips 20 can be positioned on the top and/or bottom surface of sheet 11 of surface protector 10. When one or more of the adhesive strips run along the longitudinal length of the sheet, the one or more adhesive strips are generally aligned with and run generally parallel to sides 12, 16, of the sheet of the surface protector. One or more adhesive strips can be positioned on side 12 and/or one side 16. One or more of the adhesive strips can be positioned on or spaced from side 12 and/or one side 16. If two of more adhesive strips are positioned on one or both sides of the sheet, the adjacently positioned adhesive strips can optionally be positioned next to and touch one another or be spaced some distance from one another. The adhesive strips can be positioned on only the top surface of the sheet, only the bottom surface of the sheet, or on both the top and bottom surface of the sheet. If one or more adhesive strips are located on the top and bottom surface of the sheet of the surface protector, one or more of the adhesive strips can be used to connect to another surface protector, connect to a floor surface, connect to nothing, etc. For example, the one or more adhesive strips can be used to connect one floor protector to the front and/or back ends of the sheet, and/or to one or both sides of the sheet. In another example, the one or more adhesive strips can be used to connect the floor protector to a floor surface and/or a wall surface. In another example, the one or more adhesive strips can be used to connect the floor protector to a floor surface and/or a wall surface, and one or more adhesive strips can be used to connect one floor protector to the front and/or back ends of the sheet, and/or to one or both sides of the sheet.

With reference now to FIG. 5, there is provided a perspective illustration of a surface protector 10 comprising a sheet 11 wherein adhesive strip 20 is located adjacent to edge 16 and adhesive strip 50 is located adjacent to edge 14. Both adhesive strips are located on the top surface of sheet 11. Adhesive strip 50 is illustrated as running fully from edge 12 to edge 16; however, this is not required. As can be appreciated, adhesive strip 20 can optionally be positioned on the bottom side of sheet 11. As can also be appreciated, sheet 11 can optionally include both adhesive strip 50 on the top surface and another adhesive strip on the bottom surface that is also located on or adjacent to edge 14 and runs generally parallel to adhesives strip 50; however, this is not required. As also be appreciated, a plurality of adhesive strips can be optionally positioned on the top and/or bottom surface of sheet 11 that run partially or fully between edges 12 and 14 and which run generally parallel to one another and which are located at or near edge 14.

As can also be appreciated, the top and/or bottom surface of the sheet can optionally include one or more adhesive strips that are positioned on or adjacent to edge 12 and/or edge 16 and run generally parallel to edge 12 and/or edge 16.

The different spacing and positioning arrangements of the one or more adhesive strips relative to one or both sides of the sheet of the surface protector and the top and/or bottom surface of the sheet of the surface protector allows for custom connecting to ensure adequate protection for a selected portion of a surface to be protected by the surface protector. It can be appreciated that any number of surface protectors can be utilized in conjunction with one another wherein adjacent surface protectors are overlapped, and an adhesive bond is formed between top and bottom surfaces of said adjacent surface protectors. The surface protectors can optionally be used to completely cover a floor surface. As such, during job site operations, relative movement between adjacent surface protectors is minimized or eliminated by the adhesive bond formed between said adjacent surface protectors. As can be appreciated, the arrangement, number and positioning of the adhesive strips on sheet 11 as illustrated in FIGS. 1-23 are non-limiting, and the present invention contemplates the number, configuration and arrangement of adhesive strips on the top and/or bottom surface of sheet 11.

As can be appreciated, the number and orientation of creases, and the side of the sheet upon which the one or more creases can be located, is non-limiting. FIGS. 1-4A and 6-23 merely provide a few examples of the number and orientation of creases, and the side of the sheet upon which the one or more creases can be located in combination with the one or more adhesive strips that can be located on the top and/or bottom surface of the sheet. As can be appreciated, any of the arrangements of the creases described and illustrated in any one of FIGS. 1-4A and 6-23 can optionally be used in any of the other arrangements illustrated in FIGS. 1-23.

Referring now to FIGS. 4 and 4A, one example of the folding of the sheet along a crease and the connection of two surface protectors by use of the adhesive strip is illustrated. It will be appreciated that the general principles of using the surface protector as illustrated in FIGS. 4 and 4A can be used for the surface protectors illustrated in FIGS. 1-3 and 6-12. As illustrated in FIGS. 4 and 4A, the surface protector 10 can be folded along the one or more creases. As illustrated in FIGS. 4 and 4A, when the sheet is folded along crease 22, a first portion 36 and a second portion 38 of the sheet are formed. The first portion 36 of the surface protector 10 is capable of protecting a first surface (e.g., wall W) while the second portion 38 of surface protector 10 is capable of protecting a second surface (e.g., floor F) as illustrated in FIGS. 4 and 4A. Generally, the crease is designed to be water resistant when in the bent and non-bent state.

It is to be appreciated that the lower section of wall W as illustrated in FIGS. 4 and 4A, including the baseboard (not shown), can be easily damaged at job sites. The one or more creases of the surface protector 10 are designed to enable the surface protector to protect both the floor F and the lower section of the wall W at the same time, with a single piece of material. More specifically, the surface protector 10 is designed to prevent damage at or near the junction 33 between the floor F and the wall W.

The surface protector 10 of the present invention can be manufactured as a roll of material; however, this is not required. When the surface protector is in roll form, the end user can create sheets of foldable material of desired length to cover a selected surface by cutting the sheet to a desire length after being unrolled from the roll. Generally, during manufacturing, the adhesive strip 20 can be continuously applied to the sheet as the sheet is moved along a manufacturing process. If the surface protector is to be rolled into a roll, the removable top protective release liner is applied to the top surface of the adhesive of the adhesive strip prior to rolling the surface protector.

In use, the surface protector 10 can be unrolled as illustrated in FIG. 4A and positioned on a surface (e.g., floor F, wall W) to be covered and/or protected. The surface protector 10 can optionally be folded along one or more creases (e.g., crease 22) thereby forming a first portion 36 for covering a portion of the wall W and a second portion 38 for covering a portion of the floor F. When the surface protector is to be used to protect both a wall and a floor surface, the surface protector 10 is positioned such that one of the creases is positioned at or near the junction 33 between the floor F and wall W. The removable top protective release liner can be removed from the top adhesive surface of the adhesive strip, thereby exposing the top adhesive surface of the adhesive strip on the surface protector 10. A second surface protector 70 (see FIGS. 4 and 4A) can then be provided, unrolled and subsequently positioned such that the second surface protector 70 at least partially covers the exposed top adhesive surface of the adhesive strip of the surface protector 10. Generally, the second surface protector 70 is overlapped such that the overlapping portion of the second surface protector 70 at least partially covers the adhesive surface. A pressure such as, for example, the weight of a person walking on the surface protector, moving or rolling a roller on the surface protector, moving a heavy device (e.g., a device weighing 10 lbs. or more) on the surface protector, etc., can then be applied to the top surface of the surface protector 70 in the area of the adhesive strip on the top surface of the surface protector 10, thereby completing the adhesive bonding between the surface protector 10 and surface protector 70. This process can then be repeated to secure additional surface protectors together.

As illustrated in FIG. 4, a plurality of surface protectors 10, 60, 70 can be used to protect selections of surfaces (e.g., floor F and wall W). As illustrated in FIG. 4, surface protectors 10, 60 can be folded along one or more creases (e.g., 22, 62), respectively, and positioned such that the creases (e.g., 22, 62) are positioned at or near the junction 33 between the floor F and the wall W. As such, a first portion 36 of surface protector 10 can cover a portion of the wall W and a second portion 38 of surface protector 10 can cover a portion of the floor F. Similarly, a first portion 66 of surface protector 60 can cover a portion of the wall W and a second portion 68 of surface protector 60 can cover a portion of the floor F. Surface protector 10 overlaps surface protector 60. The removable protective release liners (not shown) can be removed from adhesive strips (e.g., adhesive strips 20, 64), thereby exposing the top adhesive surfaces (e.g., top adhesive surfaces 32, 65), respectively. Another surface protector 70 can then be positioned over the exposed top adhesive surfaces of surface protectors 10, 60, respectively. As illustrated in FIG. 4, if surface protector 70 is the last surface protector to be added for protection of the selected surface, the removable protective release liner 74 is typically left in place over adhesive strip 72, thereby preventing exposure of the covered top adhesive material (not shown) of adhesive strip 72. At any point during installation, a pressure such as, for example, the weight of a person walking on the surface protector, can then be applied to the top surface of the surface protectors 10, 60, 70 in the area of the adhesive strips, thereby completing the adhesive bonding between the surface protectors 10, 60, 70. This process can then be repeated to secure additional surface protectors together.

Alternatively, the surface protector 70 can be provided, unrolled and positioned at least partially over the surface protector 10 prior to the removal of the removable top protective release liner (e.g., protective release liner 30) from the top adhesive surface (e.g., top adhesive surface 32) of the adhesive strip (e.g., adhesive strip 20) of the surface protector 10. In such a method of operation, the amount of dust, debris, etc. at the job site which sticks to the top adhesive surface of the adhesive strip before the second surface protector is applied can be minimized and/or prevented. As can be appreciated, this method of operation can be particularly useful in job operations having high dust, dirt, and/or debris production.

The adhesive bond formed between the surface protector 70 and the surface protector 10 can be a dust-proof bond. Additionally, the adhesive bond formed between the surface protector 70 and the surface protector 10 can be a liquid-proof bond.

Referring now to FIGS. 13-15, there is a provided another non-limiting embodiment of the invention. Sheet 11 is illustrated as being positioned on a floor surface or other type of surface to be protected. Sheet 11 can be in a roll that has been rolled out and cut to a desired length or can be a single precut flat sheet. Sheet 70 is illustrated as being in a roll prior to be rolled out onto the surface to be protected. As illustrated in FIG. 14, a side edge of sheet 70 overlies a top surface of a side edge portion of sheet 11. As can be appreciated, the side edges of sheet 11 and sheet 70 can be positioned adjacent to one another in a non-overlapping arrangement as illustrated in FIG. 23. FIG. 15 illustrates a strip 200 placed over the top surface of a side edge portion of sheet 70 and also over a top portion of sheet 11. Strip 200 is used to form a connection between sheets 11 and 70 and to form a dust-proof and optionally liquid-proof seal. Strip 200 can be connected to sheets 11 and 70 by an adhesive and/or a heat-created bond (e.g., melted bond, heat-activated adhesive, etc.). As can be appreciated, an adhesive connection can also or alternatively be formed between sheets 11 and 70 as described with respect to FIGS. 4-12. FIG. 23 is a variation of the embodiment illustrated in FIG. 15 wherein the edges of sheets 11 and 70 are positioned adjacent to one another and do not overlap one another. Strip 200 is used to form a connection between sheets 11 and 70 and to form a dust-proof and optionally liquid-proof seal. Strip 200 can be connected to sheets 11 and 70 by an adhesive and/or a heat-created bond (e.g., melted bond, heat-activated adhesive, etc.).

Referring now to FIGS. 16-22, there is a provided another non-limiting embodiment of the invention. Sheet 11 is illustrated as being positioned on a floor surface or other type of surface to be protected. Sheet 11 can be in a roll that has been rolled out and cut to a desired length or can be a single precut flat sheet.

A double-sided adhesive strip 210 is illustrated in FIG. 16 as being applied to a top surface of a side edge portion of sheet 11. The double-sided adhesive strip can be formed in a roll of adhesive strip as illustrated in FIG. 16; however, this is not required. As illustrated in FIG. 22, the adhesive strip 210 can optionally include a release layer 212 on one or both sides of the adhesive strip. When adhesive strip 210 includes a release layer, the release layer is at least partially removed from the adhesive strip to expose an adhesive surface so that the adhesive surface can engage and connect to the top surface of the side edge of sheet 11. The release layer on the opposite side of the adhesive strip is at least partially removed prior to sheet 70 being positioned over the side edge portion of sheet 11 that includes adhesive strip 210. FIG. 18 illustrates that sheet 70 is in a roll similar to being described above with respect to FIG. 13. As illustrated in FIG. 19, sheet 70 is rolled out over a portion of sheet 11 so that adhesive strip 210 connects together sheet 11 and 70. As can be appreciated, the side edges of sheet 11 and sheet 70 can be positioned adjacent to one another in a non-overlapping arrangement. Adhesive strip 210 optionally forms a dust-proof and/or liquid-proof seal between sheets 11 and 70. Also, the bottom surface of the adhesive strip that is not connected to sheet 11 can optionally be used to be secured to a floor surface so as to maintain the position of sheet 11 as sheet 70 is rolled out and secured to strip 210.

FIGS. 20-21 illustrates the optional further step of applying strip 200 over the top surface of a side edge portion of sheet 70 and also over a top portion of sheet 11. Strip 200 is used to also form a connection between sheets 11 and 70 and optionally also to alternatively form a dust-proof and/or liquid-proof seal between sheets 11 and 70. Strip 200 can be connected to sheets 11 and 70 by an adhesive and/or a heat-created bond (e.g., melted bond, heat-activated adhesive, etc.). As can be appreciated, an adhesive connection can also or alternatively be formed between sheets 11 and 70 as described with respect to FIGS. 4-12.

It is to be appreciated that the surface protector 10 of the present invention can be used in conjunction with existing types of surface protectors and/or floor coverings (e.g., plastic sheets, cardboard, fiberboard, cloth, etc.) for the purpose of protecting selected portions of surfaces.

It is also to be appreciated that a plurality of surface protectors 10 can be used to completely cover the floor and at least a lower portion of one or more walls at a job site.

It will be appreciated that variants of the above-disclosed and other features and functions, or alternatives thereof, may be combined into many other different systems or applications. Various presently unforeseen or unanticipated alternatives, modifications, variations or improvements therein may be subsequently made by those skilled in the art which are also intended to be encompassed by the following claims.
